The value of conducting environmental and social screening at the early conception and planning phase of a road development project is to provide useful technical input to the road project team for their planning and budgeting, thereby eliminating the possibility of costly remedial environmental work and delays caused by problems with adverse environmental damage. Such early input on environmental considerations also provides useful information that helps the project team to gain government approval and win public acceptance.
